Default Q6600 + GKnot + Divx

Hi,

is anyone using the quad Q6600 with Gordian Knot with Divx5 codecs? I'd like to know if GKnot/Divx5 combination makes full use of the 4 cores as it does with 2...


Thanx

would do that gladly had I had a Q6600 .

I'm looking around for a Q6600 rig, due to the recent price reduction
On some forums I've seen discussion about the real impact of a quad core and it turns out that it all depends on the software (that is why I mentioned GK+Divx that interests me).

Some software simply "ignores" the presence of any further core beyond the second one and so voiding any interest for a quad core.

GK+Divx takes advantage of a 2 core cpu (80-100% on both, sustained) but wondered if it scaled accordingly with a 4core cpu or not (Photoshop seems not to, for example, so a fast dual core is better than a quad with it).

Q6600 2.4Ghz beats higher clocked Dual Core @ 3ghz, so I'd say it makes good use of the extra cores

Jmke,

at the moment I'm with Divx5 and loath about going Divx6 for lack of (personal) tests about compatibility with my hardware and quality/space.

The scalability depends much on the encoder used (it seems for example that the Xvid encoder is not very keen on a quad core, MEGUI+H264 seems very happy with 4 cores on the other hand) and hoped for specific Divx5 test...

Thanx for the info anyway!

ah, feature difference 5<>6 is also in multi-threading? didn't know, sorry

oh no, I'm not saying that: I just did a few test with Div6 one or two years ago and surely did not test the multithreading aspect: at the time I did not even have a dual core cpu.

It's just that I'm using the Divx5 codecs and for the moment I have no intention of moving to Divx6 , and since the multithreading ability is so depedent ont the implementation of a particular codec, knowing that Divx6 scales up nicely to 4 cores does not necessarily mean that the Divx5 does so as well.
